ELT a. First galaxies and epoch of reionisation Paolo Padovani b. High - energy astrophysics in our Galaxy and AGNs Giuseppe Bono c. Characterization of exoplanets Michele Cirasuolo (TBC)

Many other potential applications of this dataset are explored in the series of papers, and they include studying the role of faint galaxies during cosmic reionisation (starting just 380,000 years after the Big Bang), galaxy merger rates when the Universe was young, galactic winds, star formation as well as mapping the motions of stars in the early Universe.

By doing so, they have established that the epoch of reionisation — which ends at the point when the Universe is fully transparent — came to a close about 700 million years after the Big Bang [3].

«This transitional period is known as the reionisation era.

The hot stars carve out transparent bubbles in the gas and once all these bubbles merge to fill all of space, reionisation is said to be complete and the Universe becomes transparent to ultraviolet light.

By looking at the light coming from the galaxies the team discovered that the accumulated light emitted by these galaxies could have played a major role in one of the most mysterious periods of the Universe's early history — the epoch of reionisation.

The burst's immense distance makes the now - dead star the earliest object to be discovered from an era called «reionisation `, which occurred within the first billion years after the big bang.

The timing of the period of reionisation is still unclear, Bloom says.

The SKA will detect neutral hydrogen and the onset of reionisation, and it will trace the reionsation history of the Universe up to the present time.

Artist's impression of a portion in the timeline of the Universe, around the «epoch of reionisation» — the process that ionised most of the material in the cosmos.

In particular, SPICA will have the unique ability to trace the evolution of the obscured SFRD and BHARD over cosmic time, from the peak of their activity back to the reionisation epoch (i.e., 3 < z < 6 - 7), where its predecessors had severe limitations.

Tracing the evolution of dust obscured star - formation and accretion back to the reionisation epoch with SPICA

The galaxy appears to us as it was when the Universe was only 600 million years old, during the period when the first stars and galaxies were forming [1] This time corresponds to a redshift of z = 8.38, during the epoch of reionisation..

If the quasar is so distant that the light we observe from it escaped during the «dark ages», its UV light will have been absorbed by the neutral hydrogen present at the time; if the quasar is closer and the light we observe was emitted only after the reionisation, there will have been no neutral hydrogen to impede it (see diagram below).

Astronomers have labelled this important event as «reionisation».
